Starting from linux-3.15 (commit 9063e21fb026, "netlink: autosize skb
lengths"), kernel is able to send up to 16K in netlink replies.
This change enables iproute2 commands to get bigger chunks,
without breaking compatibility with old kernels.

Such approach allows to run *.t scripts from any
tests/ subdirectories.
One point is that tests from tests/cls/*.t (which are needed
by tests/cls-testbed.t but does not exist yet) will also
be ran aside with tests/cls-testbed.t which is not good
because in such case they will be ran twice, so renamed these
tests path to tests/cls/*.c in tests/cls-testbed.t

Allow to print particular link type usage by:
ip link help [TYPE]
Currently to print usage for some link type it is needed
to use the following way:
ip link { add | del | set } type TYPE help

'ip -oneline tunnel show' was not "oneline" for GRE tunnels with iseq:
# ip tun add gre_test remote 1.1.1.1 local 2.2.2.2 mode gre iseq oseq
# ip -oneline tun show gre_test | wc -l

The problem existed because of a typo: '\n' was printed when it shouldn't be.
Fixed.

Make ip address show accept the -s option similarly to ip link. This creates
an one command replacement for "ifconfig -a" useful for people who still
stay with ifconfig because of this feature.
Print the stats as the last thing for the interface. This requires some code
shuffling.

Since commit 3c682146ae, iplink requires assigning negative
ifindex (-1) to the kernel when creating interface without
specifying index.
v2: checking whether index is -1, suggested by Cong Wang.

The man page and the "fail" example are missing an underscore in the
nf_mark ematch.
eg.
tc filter add dev eth0 parent ffff: basic match 'meta(nfmark gt 24)'
classid 2:4
meta: unknown meta id
... >>meta(nfmark gt 24)<< ...
... meta(>>nfmark<< gt 24)...
Usage: meta(OBJECT { eq | lt | gt } OBJECT)
where: OBJECT := { META_ID | VALUE }
META_ID := id [ shift SHIFT ] [ mask MASK ]
Example: meta(nfmark gt 24)
meta(indev shift 1 eq "ppp")
meta(tcindex mask 0xf0 eq 0xf0)
For a list of meta identifiers, use meta(list).
Illegal "ematch"
meta(list) does correctly show nf_mark and the above test works with
nf_mark.

Tests were not allowed to be ran, the following

- creating the results folder before test running
- sudo $PREFIX moved before variables definition which

Was broken by commit 288abf513f
Lets not be too clever and have a separate call to print flushed
actions info.
Broken looks like:
root@moja-1:~# tc actions add action drop index 4
root@moja-1:~# tc -s actions ls action gact
action order 0: gact action drop
random type none pass val 0
index 4 ref 1 bind 0 installed 9 sec used 4 sec
The fixed version looks like:
action order 0: gact action drop
random type none pass val 0
index 4 ref 1 bind 0 installed 9 sec used 4 sec

This patch adds the necessary changes to allow altering a slave device's

This is ugly fix but solves the case when timestamp
or banner-label is printed before the cloned route will be skipped
by iproute filter which filters out all cached routes by default.
In such case timestamp will be printed twice:

Update the rt_dsfield file to contain values defined in current RFC.
The days of TOS precedence are gone, even Cisco doesn't refer
to these in the documents.
The real checking is performed later in iplink_modify(..) func which
checks device existence if NLM_F_CREATE flag is set.
Also it fixes the case when impossible to add veth link which was
caused by 9a02651a87 (ip: check for missing dev arg when doing VF rate)
because these devices are not exist yet.
